* <p>This class is available mainly for application writers, who
* can use it to make a persistent snapshot of a locator at any
* point during a document parse:</p>
*
* <pre>
* Locator locator;
* Locator startloc;
*
* public void setLocator (Locator locator)
* {
* // note the locator
* this.locator = locator;
* }
*
* public void startDocument ()
* {
* // save the location of the start of the document
* // for future use.
* Locator startloc = new LocatorImpl(locator);
* }
*</pre>
*
* <p>Normally, parser writers will not use this class, since it
* is more efficient to provide location information only when
* requested, rather than constantly updating a Locator object.</p>
*
* @since SAX 1.0
* @author David Megginson
